I was asked to model and render instruments made of paint for Colorificio Sammarinese. They wanted to use those on their paint buckets etc. My first idea was to work with realflow or some other particle system to create this effect but down the road any changes to the shapes etc might be very hard to control. So I used my beloved ZBrush. And it was just when the dynamesh appeared first time so I could do whatever client asked and wasn't puling my hair out when there where some drastic changes :)
